This document defines a C language application program interface to the lightweight directory access protocol (LDAP). This document replaces the previous definition of this API, defined in RFC 1823, updating it to include support for features found in version 3 of the LDAP protocol. New extended operation functions were added to support LDAPv3 features such as controls. In addition, other LDAP API changes were made to support information hiding and thread safety. The C LDAP API is designed to be powerful, yet simple to use. It defines compatible synchronous and asynchronous interfaces to LDAP to suit a wide variety of applications. This document gives a brief overview of the LDAP model, then an overview of how the API is used by an applica- tion program to obtain LDAP information. The API calls are described in detail, followed by an appendix that provides some example code demon- strating the use of the API. This document provides information to the Internet community. It does not specify any standard.
